Windows/Mac: AirPlay is an awesome way to stream your music to your big stereo, but it only really works with iTunes. Airfoil streams any audio to you AirPlay devices, and it's $10 off right now.

That means if you're listening to music through Pandora, Spotify, Winamp, or other AirPlay-incompatible apps, Airfoil will let you stream it anyway. It's one of the best ways to make your entire home AirPlay-compatible, but it's usually a tad pricey at $25. In honor of their tenth anniversary, Rogue Amoeba (makers of Airfoil) are selling their entire library of apps for $10 off, which means Airfoil becomes a much more enticing $15. You can also grab their other popular apps, like Audio Hijack Pro, Piezo, and more, with the same $10 discount. The sale lasts until Sunday. Hit the link below to read more.
